docker.ubuntu's Issues

on ubuntu 15.04 service doesn't start on server reboot

Hello,
I use this role to provision an ubuntu server, if the server restarts docker doesn't start with it.
Is there a way to setup that in this playbook ?

Thank you

Ansible distribution conditional stops me from executing on a 14.04 box.

Hi, i'm executing the role against a 14.04 box and got this:

TASK: [angstwad.docker_ubuntu | Fail if not a new release of Ubuntu] ********** 
fatal: [localhost] => error while evaluating conditional: ansible_distribution_version|version_compare(12.04, '<') or ansible_distribution_version|version_compare(12.10, '=')

I have use debug to print my box ansible_distribution version:

TASK: [debug var={{ansible_distribution_version}}] **************************** 
ok: [localhost] => {
    "14.04": "14.04"
}

$>ansible --version
ansible 1.5.4

Wrong link in repository description

GitHub repository description points to a 404 link. The correct one is: https://galaxy.ansible.com/list#/roles/292. Can you please fix it?

Allow ssh port override and disable sudo on local_action

It would be helpful to allow the ssh port to be overridden based on the inventory file settings. I can submit a PR if you'd like but its really just changing the two lines in tasks/main.yml

- name: Wait for instance to come online
  local_action:
    module: wait_for
    host: "{{ hostvars[server_name]['ansible_ssh_host'] }}"
    port: "{{ hostvars[server_name]['ansible_ssh_port'] }}"
    delay: 30
    timeout: 600
    state: started
  sudo: no
  when: "ansible_distribution_version == '12.04' and reboot_result|success"

EDIT: Additionally, explicitly disabling sudo for the local_action port check is nice. It seems that local_action with sudo enabled is annoying and requires

/etc/sudoers to have NOPASSWD enabled for the user OR
possibly setting the sudoers password when running ansible

I didn't try the second approach honestly, as disabling sudo works just as well if not arguably better.

Version on Ansible Galaxy is outdated?

I see that the code pulled via ansible-galaxy is old. Is it recommended to point at github repo as the source in requirements.yml?

So I ran vagrant ssh and ran sudo apt-get update inside the machine and got this error

Also, after receiving that error, my ssh connection breaks.

Looks like a problem with the version of docker-py and docker-compose. As a temporary solution, I've noticed there are variables that can be passed to use a specific version: pip_version_docker_py, pip_version_docker_compose. I've tried passing version '1.5' for both items but didn' t help. Any suggestion?

No release

Hello,

Can you create a release ? and update your role in galaxy to add this release ?

Thanks,

version checking can give unexpected results

version_compare(12.04, '<') can lead to unexpected comparison result, version_compare('12.04', '<') should be used instead.

Support forcing install from docker's repository

Hey,
in recent commit this role now always installs docker using the Ubuntu stable repository docker.io package if you're on Ubuntu 14.04.
This is not so good since the verison of docker it supports is 1.01 where as the latest docker available on Docker's own repository is 1.3

It would be nice to add a flag that can be set to force always installing from docker's repository (e.g the lxc-docker package).

If sounds reasonable I can send a pull request

Cannot install kernel extras but not upgrade the current running kernel

When setting:

kernel_pkg_state: present
install_kernel_extras: true

The expected behaviour should be to install the current kernel extras. However a kernel upgrade is performed. I believe the problem is because you are installing linux-image-extra-virtual and that is not versioned so it'll trigger a kernel upgrade regardless.

This is on Ubuntu 14.04

Thanks

'ansible_docker0' is undefined

Getting an error when using the docker.io package instead of lxc:

TASK: [docker.ubuntu | Fix DNS in docker.io] **********************************
fatal: [ubuntu-access-bm] => One or more undefined variables: 'ansible_docker0' is undefined

DOCKER_OPTS not loaded on 15.10

It seems that the DOCKER_OPTS variable either isn't being loaded or isn't being read when systemd goes to start Docker. This results in, for example, being unable to expose the docker daemon on a port.

The referenced PR is a hack to get around this problem, though I suspect the root cause is PEBKAC. If there is a better way around this I'd love to throw my PR away.

I am using the ubuntu/wily64 Vagrant box. For reference, my playbook.yml is as follows:

- hosts: all
  sudo: true
  roles:
    - role: roles/docker.ubuntu
      docker_opts: >
        -H unix://
        -H tcp://0.0.0.0:2375
        --log-level=debug

option to skip installing Python stuff

I don't need docker-compose or docker-py, so the pip installs of these packages are superfluous. It'd be great to have an option to skip their install.

Unable to remove filesystem

I'm using the role like this:

- name: Start sandbox
  docker:
    name: blah
    image: caarlos0/blah
    pull: always
    state: reloaded
    ports:
      - 5000:5000

It works the first time, but if I try to run it again, I got:

docker_ubuntu unexpectedly alters Ansible environment

I must execute docker_ubuntu role with become: yes because it requires administrative privileges to do the tasks. The final task in docker_ubuntu performs a setup action, which alters variables. In my case, tasks in roles following the docker_ubuntu role needed to use the HOME environment variable, but the call to setup caused my environment to be set to root's environment (and therefore, HOME to be set to /root).

Is there a way to avoid calling setup, or at the very least, can it please be much more tightly restricted (see the available options for setup)? I don't understand to what this docker.io relates. It appears to be a deprecated name for the Docker package. If it is, could this please be removed entirely?

Needless "changed"

I'm not sure about how the pip module works, but is really necessary that every time a playbook runs the following should happen (the 2 last install are always changed):

TASK: [angstwad.docker_ubuntu | Upgrade latest pip, setuptools, docker-py and docker-compose with pip] ***
ok: [fe-web1-acc] => (item={'version': u'latest', 'name': 'pip'})
ok: [fe-web1-acc] => (item={'version': u'latest', 'name': 'setuptools'})
changed: [fe-web1-acc] => (item={'version': u'latest', 'name': 'docker-py'})

Breaks due to some Pip issues

I've been using this role for a while, but recently have it making my builds fail trying to install docker-compose. I get this:

Nothing in my scripts changed. Seems like this is an issue with new docker-compose installation (which I'm not sure is even needed for this role in the first place).

installs both docker.io and lxc-docker

This role installs both docker.io (from Ubuntu) and lxc-docker (from Docker), which are conflicting packages. So every time you rerun this role it uninstalls lxc-docker, then installs docker.io, then uninstalls docker.io and installs lxc-docker when a rerun should just be a no-op.

Why does it do this and how can we prevent it? This information should be present in the README.

Missing config for specifying version for pip package `docker-py` version

I am using docker 1.3.3, and docker-py 0.6.0.
On a new machine, I found out this role installed docker-py 0.7.0, which uses a newer API version, and return error on every docker module task.

- name: Install Docker-py with correct version
  pip:

Getting errno 2 when trying to install docker on remote machine

Hi,

I have a really simple ansible playbook that is failing on the first task of the docker install.

name: Install the dbserver components
hosts: dbservers
vars_files:
- "group_vars/dbservers.vars"
  user: gmuser
  sudo: yes
roles:

The var file contains,

kernel_pkg_state: present

The way I execute the playbook is,

ansible-playbook -i development sites.yml --ask-pass --ask-sudo-pass

I leave the ssh and sudo password the same. The error I get is,

The remote machine is running Ubuntu 12.04 and currently has the Precise kernel and Docker 1.1.1 installed.

When I try to apt-get install the raring kernels from an ssh terminal, I get no errors.

potential data integrity issue if storage options are customized during role execution

I think have found an issue if this role is used together with custom storage options designed to enable direct-lvm mode https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/

The issue arises because after the DOCKER_OPTS variable is configured, there is no restart of the docker daemon. As a result, the initial install of the docker daemon will be running with the thin pool device mapped to the loop back device instead of the thin pool device of the intended volume group. When the docker daemon is subsequently restarted the thin pool device implied by the storage options will be used which, of course, is a different device.

docker.ubuntu should install Python packages only with consent from user

PR #92 introduced a number of helpful new options to install docker-py, docker-compose, and supporting Python packages. At the moment, these are all set to true, meaning that an unsuspecting user of docker.ubuntu will have pip, a new version of setuptools, docker-py, and docker-compose installed on her machine.

While most users will appreciate these tools, as a principle, it seems better to seek the user's consent, rather than install software the user may not need, especially without the user's awareness. In other words, follow the Principle of Least Surprise. docker.ubuntu seems to follow this philosophy for other items, for example, the linux-image-extras. So this brings the installation of Python-related tooling to be consistent with that philosophy.

I see a couple of inter-related issues here:

Avoid installing extra Python packages by default

All of the pip install settings in the defaults should change to false.

This also includes the installation of pip itself via apt installation of python-pip and python-dev. This action should happen with the user's consent. Document these options as a convenience provided by docker.ubuntu if they want to install the Docker-related tools.

Disallow contradicting settings

There exists a chance for contradiction in the settings, whereby, the user can specify true to install a tool like docker-compose, yet false for a dependency like pip. I see two solutions:

Implicit approval of dependencies

In this solution, explicit user-approval for a tool creates implicit user-approval of the tool's dependencies. Setting pip_install_docker_compose to true implies that pip must be available on the system. Similarly, setting pip_install_docker_py also implies that pip must be available. This dependency should be captured, and the need to install pip should be computed as a dependency, and installed if either setting is set to true (or both settings are set to true).

In this case, it seems best not to even expose an option on controlling the installation of pip, itself. Document the dependency, and that user consent to pip_install_docker_py/pip_install_docker_compose implies consent to install the necessary Python dependencies. Consider the case where the user sets pip_install_pip to true, but pip_install_docker_py and docker_compose both to false. This would cause docker.ubuntu to providing functionality unrelated to Docker (installing pip).

Explicit approval, error out with contradictory settings

In the second scenario, all the configuration values remain (but still set to false by default). When the user enters an incompatible combination, such as pip_install_pip: false and pip_install_docker_py: true, issue an error warning of contradictory settings.

I think this option will be more frustrating to the user.

Side-issue: Install pip using a role

There are a number of roles on Ansible Galaxy for installing pip; would it be possible to use one of those as a dependency? Alternatively, since this is a pretty small installation, at least consider turning the installation of pip into a first-party role inside docker.ubuntu. Then installation of docker-py and docker-compose can create a dependency on that role.

docker-py 1.10.0 Seems to be broken

This isn't a problem with docker.ubuntu, but maybe it should be pinned to 1.9.0 until it is resolved:
After installing docker.ubuntu, when you try to actually do any docker commands, in this case, docker_login

{"changed": false, "failed": true, "msg": "Failed to import docker-py - No module named types. Try `pip install docker-py`"}

Proposed method of specifying docker_opts - doesn't work

Recommended way to specify options doesn't work. Example is bellow

My opts variable looks like this

# The following help expose a docker port or to add additional options when
# running docker daemon.  The default is to not use any special options.
#docker_opts: >
#  -H unix://
#  -H tcp://0.0.0.0:2375
#  --log-level=debug
docker_opts: >
  -H unix:///var/run/docker.sock
  -H tcp://0.0.0.0:2376
  --tlsverify 
  --tlscacert=/etc/ssl/certs/docker-ca.pem 
  --tlscert=/etc/ssl/certs/{{ hostname }}-cert.pem
  --tlskey=/etc/ssl/private/{{ hostname }}-priv-key.pem
# List of users to be added to 'docker' system group (disabled by default)
...

It produces followed result:

$ cat /etc/systemd/system/docker.service.d/env.conf 
[Service]
Environment="DOCKER_OPTS=-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2376 --tlsverify --tlscacert=/etc/ssl/certs/docker-ca.pem --tlscert=/etc/ssl/certs/docker-host-n1-cert.pem --tlskey=/etc/ssl/private/docker-host-n1-priv-key.pem
"

Because double quotes located on the new line, no parameters are actually applied.

I fixed it by specifying opts in old-style-one-line way:

docker_opts: "-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2376 --tlsverify --tlscacert=/etc/ssl/certs/docker-ca.pem --tlscert=/etc/ssl/certs/{{ hostname }}-cert.pem --tlskey=/etc/ssl/private/{{ hostname }}-priv-key.pem"

And now it works fine

/etc/default/docker does not exists on Ubuntu 14.04

See this comment: e1380bf#commitcomment-9975113

Related issue: #23

'module' object has no attribute 'DEFAULT_DOCKER_API_VERSION'

Version 1.2 of Docker-Py has broken the Ansible docker plugin. They've committed a fix, but it hasn't been released in a stable version.

In the meantime, docker.ubuntu can resolve by forcing pip to install version 1.1 of Docker.py instead of using the latest.

(See discussion: ansible/ansible#10879)

docker_pkg_name changed?

I've been using this for a while and noticed that docker_pkg_name no longer works the way it used to. The default package is now docker-engine and you can no longer install specific packages with options like: docker_pkg_name: lxc-docker-1.6.2. Is there a new workaround here to peg the version? Installing whatever version happens to be the newest feels very dangerous.

Ensure latest installation instructions are being followed

I noticed the 12.04 installation instructions are a bit out of date. Let's take a look at the tasks and ensure we're following the "supported" installation procedure, and community best practices wherever applicable.

resolv.conf set to 8.8.8.8

repo with packer build that is my exact setup on how I got this error:
https://github.com/joshuacox/dacksible
anyone should be able to cd into the packer directory and make vbox to get the exact error as above. Given that you have virtual box, vagrant, and packer installed amongst any other dependencies I'm forgetting.

I'm sure I'm doing something wrong as I'm still abit new to Ansible, but if anyone can shed some light on why this is failing I'd love to figure it out.

docker module: incompatible with docker-py 1.2.x

See here and here for more details. Workaround is installing an older version of docker-py:

  tasks:
    - name: Install docker-py
      pip: name=docker-py version=1.1.0

And it could be set with pip_version_docker_py.

I'm not sure about a proper way to solve this. One of the solutions could be setting default pip_version_docker_py to 1.1.0 if ansible version is below some value.
